When i reset them by holding OK and then do a factory reset they always get the settings from somewhere and the extensions reappear. I cant login to the admin panel as the password even after the reset is not admin/admin.

Can anyone please help ?

They are on firmware


This is because the phone is running on customized firmware (xx.xx.179.x)
Please contact the provider/distributor of this firmware and ask them if they are willing to help you out.

Sorry, wrong answer. Blush
The phone is probably locked with its MAC address to the RPS of your VoIP provider.
So if you reset the phone to factory default and the phone reboot, it will get all info again from the RPS server including passwords.
Please contact your provider and ask him to remove the MAC address from his RPS server.

Hope this will help.

Kind regards,

Please do not send unsolicited PM messages. I will not answer them.
